I don't know what you mean by frozen, so maybe this is no good, but I would avoid having aModule look back at the state of mainApp. Instead use another module to communicate state. This could be a simple as

# in mainApp
import helper
if something:
  import oneMod as theMod
else:
  import orTheOtherMod as theMod
helper.theMod = theMod

import aModule

# in aModule
import helper.theMod as theMod
theMod.someFunction()
